RIDING ATTACHMENT FOR HARRows."

SPECIFICATION forming part of Letters iatent No. 746,146, dated December8, 1903.

I Application filed July 2s,19o3. Serial No. 167.352. (No model.)

To all whom it may concern:

Be it known that I, ALBERT WYMAN PERRY, a citizen of the United States,residing at Northviile, in the county ofSpink and State of South Dakota,have invented anew and useful Riding Attachment for Harrows, of whichthe following is a specification.

This invention relates ,to riding attachments for harrows, especiallyfor that class of harrows which are known as drags and which comprise intheir construction a plurality of suitably-connected frame-bars havingdownwardly-extending teeth or spikes.

My invention has for its'object to provide a riding attachment whichshall be simple in construction, easily applied or connected with aplurality of drags, and which shall be in all respects convenient andeasily manipulated.

With these ends in View my invention consists in the improvedconstruction, arrangement, and combination ofparts, which will behereinafter fully described, and particularlypointed out in the claims.

In the accompanying drawings I have shown a simple and preferred form ofembodiment of my invention; but it will be understood that I reserve theprivilege to any changes in theconstruction, size, proportion, or mannerof assemblage of the parts of the device which shall be within the scopeof my invention.

In said drawings, Figure 1 is a plan view of a device constructed inaccordance with the principles of my invention. Fig. 1 is a detail viewshowing the connection of the frame-pieces with-the casting 8. Fig. 2 isa side elevation of the same. Fig. 3 is a trans verse sectional viewtaken longitudinally through the axle ofthe supporting-wheel of thedevice. Fig.4 is a perspective detail view showing the bearing for theupper end of the fork carrying the supporting-wheel. Fig; 5 is asectional detail view showing the means for connecting the drag-barwith'the feet of the barrow-frame. Fig. 6 is'a sectional detail view ofone of the segments utilized for efiectingthe raising and lowering ofthe barrow-sections. Fig. 7 is a detail side view of one of saidsegments.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

The frame of my improved riding-barrow is composed of two sides 1 1,provided at their front ends with downturned diverging members or legs 33, terminating in approximately horizontally disposed feet 4 4, theknees or bends being designated 5. the feet 4 extend from the legs 3 areshort angular portions 6-,the object of which will be hereinafterdescribed.-

The rear ends of the side membersl of the At points where frame arebent'to form loops 2 2, which are connected pivotally, as by means ofpins or bolts 7, with a casting 8, the rear end of which is horizontallybifurcated for the reception of the said loops or eyes 2, which are thusconfined loosely in the recess 11, formed by the bifnrcation'of thecasting 8. The said casting is supported uponacaster-wheel12, journaledin a fork 13, the members of which converge at their upper ends, saidmembers 14 being between the members 14 of the fork 13. The

casting 8supports a spring 21, carrying a seat 22, which is mountedadjustably upon the uppera'pproximatelyhorizontal portion of saidspring, which is provided with perforations', as 23, to receive afasten'ing-bolt 24. The seatspring is connected with the casting 8 bymounting it upon the upper reduced end of the spindle 16, the nut 17thus serving to connect the spindle, the casting, and the seatspring.The fork 13 has a step-25 attached to it to assist the driver inmounting.

The side members 1 l of the main frame are connected a suitable distancein rear of the knees 5 by means of a transverse bracebar 26, which ispermanently connected with said side members in any convenientmanner.The brace 26 is connected,'by means of a stout connecting-rod 27, withthe front end of the casting 8, thus maintaining the latter in anormally horizontal position and strengthening and bracing the partsrelatively to each other. The connecting-rod 27 carries a footrest 27.To the side members 1 1 of the main frame, close to the knees 5, issecured a transverse bar 28, having a plurality of uprights 29, whichsupport revoluble shafts 30. The latter carry a plurality of segments,designated, respectively, 31 and 32. Upon the cross bar or brace 26 aremounted aplurality of levers 33, to which above their fulcra areconnected chains 34, which extend forwardly over the segments 32, withthe front ends of which they are connected, said front ends or pointsbeing provided with hooks 35, with which said chains are adjustablyconnected.

The feet 4 of the frame are provided with transverse perforations 36,adapted for the attachment adjustably with relation to the said feet ofclevises 37, the under sides of which are connected,by means of bolts38,with a transversely-disposed drag-bar or evener 39, which, as will beobserved, extends across the entire width of the frame and beyond thelatter, if necessary. It will also be noticed that the means by whichthe drag-baris coupled to the frame will admit of said drag-bar workingfreely and loosely and without any degree of stiffness or rigidity,which would impart a jolting movement to the entire device. The drags orharrow-sections are connected with the bar 39 by means of linkconnections 41, whereby they are permitted to move freely in such amanner as to operate upon the soil in the most satisfactory manner.These drags or barrow-sections are in the present instance composed oflongitudinal obliquely-disposed bars 42, connected by cross-bars 43. Oneof these cross-bars of each barrow-section is connected by means ofchains 44 with the segments 31 upon the revoluble shaft 30, said chainsbeing connected with the rear ends'of said segments, which are providedwith hooks 45 for the adjustable attachment of said chains.

It will be seen from the foregoing description that when the levers 33,the normal position of which is upright, are thrown back to anapproximately horizontal position they may be maintained by placing themin engagement with hooks 46, located upon the frame. The revolnble orrocking shaft 30 will be oscillated in its bearings, thus winding thechains 44 upon the segments 31, and consequently raising or tilting theharrowsections. I would state that the chains 44 are connected with thebarrow-sections in front of the longitudinal centers of the latter, sothat the greater weight of said harrow-sections shall be in rear of saidpoints of attachment. The object of this is to cause the front ends ofsaid barrow-sections to be raised first, so that said front ends may beaccommodated above the drag-bar and in the angular portions 6 of theframe-bars, when it will be seen that the front teeth of saidharrow-sections will be raised clean from the ground and retained inthis position while the rear ends of the harrow-sections are beingelevated to the desired height. When in this position, the harrow isready for transportation from one field to another or over the roads, asmay be desired. tilting or elevating the harrow-sections may also beperformed at any time during the practical operation of the harrow inorder to clear the teeth of the barrow-sections of weeds and trash whichmay have accumulated therein.

The preferred construction'of the segments 31 and 32 is illustrated inFig. 6 of the drawings. Inasmuch as these segments are constructedpractically alike, I have shown only one of them--namely, one of thesegments 32. This is composed of a cast-iron disk 47, having a hub 48,through which extends a setscrew 49, whereby it may be firmly secured inthe desired position upon the rock-shaft 30. To opposite sides of thedisk or plate 47 are riveted sheet-metal flanges 50, between which issecured, likewise by means of rivets, a bent sheetmetal strip 51, havinga U- shaped groove 52, in which the chain connected with said segmentmay ride. I have also in Fig. 3 of the drawings shown a preferredconstruction of the hub for the casterwheel 12. In said figure 53designates the axle, which has its hearings in the members 14 of thefork 13. Said axle is provided with reduced screw-threaded ends 54 and55, extending through suitable perforations in the fork-arms 14. Thelength of the axle exceeds that of the hub 56 of the caster-wheel, whichsaid hub contains an axle-box 57. Flanged sleeves 58, forming washers,are disposed adjacent to the ends of the axle-box, and springs 59,coiled upon the said sleeves, exert their tension between the flanges 60of the sleeves 58 and washers 61, which are placed upon the axleadjacent to the inner sides of the forkarms, thereby forcing the flangesof the sleeves into contact with the axle-box of the casterwheel andpreventing the entrance into said axle-box of sand and dirt, which wouldinjuriously affect the said members.

From the foregoing description the operation of my invention will bereadily understood. -By manipulating the levers 33 the barrow-sectionsmay be raised or lowered, as may be desired, and by placing the saidlevers in engagement with the hook 46 the barrow-sections will beretained in a raised position, so as to enable the harrow to beconveniently transported from one place to another.

Having thus described my invention, I claim- 1. In a riding attachmentfor harrows, a frame having rearwardly-converging side pieces,downwardly and forwardly diverging legs, horizontally-disposedtransversely-perforated feet at the lower ends of said legs, clipsengaging said transverse perforations, bolts extending downwardly fromsaid clips, and a drag-bar mounted upon said bolts and The operation ofbeing thus flexibly connected with the of the barrow-frame.

2. In a riding attachment for harrows, a frame havingrearwardlyconverging side pieces, a brace connecting said side pieces, ahorizontally-bifurcated casting loosely engaging the curved rear end ofthe frame, and a rod connecting the front end of said casting with thetransverse brace. v

In a riding attachment for harrows, a frame comprisingrearwardly-convergin g side pieces, downwardly and forwardly diverginglegs terminating in horizontally -disposed feet, a-drag-bar flexibly.connected with said feet, harroW-sections flexibly connected with saiddrag-bar, a transverse brace-bar connecting the sides of the frame, ahorizontallyfeet ' bifurcated casting engaging the curved rearrow-sections flexibly connected'Wit-h said drag-bar, a transversesupporting-bar upon the frame, uprights upon said supportingbar, arock-shaft journaled in said uprights, segments upon said rock-shaft,chains connecting said segments with the barrow-sections in front of thecenters of gravity of the latter, additional segments upon therockshaft, levers fulcrumed upon the frame, and

chains connecting said levers adjustably with the additional segmentsupon the rock-shaft.

5. In a riding attachment for harrows, the combination with a frame,of arock-shaft having a plurality of segments mounted securely a castingflexibly connected with the curved rear end'of the frame, a rodconnecting the front end of said casting with the transverse brace, aspindle extending downwardly from said casting, said spindle beingprovided with a reduced threaded upper end extending through aperforation in said casting, aseatspring mounted upon the reduced end ofsaid spindle, above the casting, a nut connecting said spindle andseat-sprin g with the casting, a caster-wheel, a fork carrying the same,and

a socket clamped between the upper ends of i I the members of the forkand engagingthe spindle extending downwardly from the casting connectedwith the frame.
